  1. TurtleMetamorphoses From “FD 1” To 3D Animated Characters Pavel Boytchev www.elica.net Eurologo 2003, Porto, Portugal

  2. Turtle Metamorphoses • Logo and Turtle graphics • Elica as a tool for evolutional experiments • Examples

  3. Logo and Turtle graphics • Almost 130 Logo implementations • Does the evolution hit a dead end? • The thing that holds up turtle evolution is...

  4. Logo and Turtle graphics The thing that holds up Turtle evolution is… ...its integration with the Logo language

  5. Elica features: 10 built-in commands No turtle support Total user control Elica as a Tool for Experiments Elica goals: • To build Logo itself as a microworld • To bring into being Turtle graphics • To conduct Turtle evolution
